Just One Pure ITer

早在 2014 年，携程的一些业务部门开始引入 Kafka 作为业务日志的收集处理系统。2015 年，基于 Kafka 的高并发、大数据的特点，携程框架研发部在 Kafka 之上设计了 Hermes Kafka 消息系统，作为大规模的消息场景的统一的中间件。随着业务量的迅速增加，以及具体业务、系统运维上的一些误用，Kafka 现有系统变得不稳定，经历了多次 down 机，故障期间完全不可用，持续时间长达 5 小时以上，恢复缓慢。Kafka 还能用多久？成为一个迫切棘手的问题。问题严重又难以解决，必须做出改变。
本文主要分享携程将 Kafka 从 0.9 升级到 2.0 的实战经验以及基于 Kafka 2.0 的应用实践。这是 InfoQ 特别策划《Kafka 的七年之痒》专题系列文章的第三篇，前两篇文章回顾见 《Kafka 从 0.7 到 1.0：过去 7 年我们踩过哪些坑？》、《杠上 Spark、Flink？Kafka 为何转型流数据平台》。
